SPECIFICATION forming part of Letters Patent No. 395,492, dated January 1', 1889.

Application filed July 12, 1888. Serial No. 279,703. (No model.)

and it consists in the improved electric gov- 1 To give a double bearing to said arms,whereernor having the arrangements and combinaby they are held more firmly upon the stand- 2o tions of parts substantially as will be hereinard or shaft (1, and to relieve the upper bearafter set forth, and finally embodied in the ing of a part of the lateral strain, I prefer to i clauses of the claim. provide a guideway in which the said arms Referring to the accompanying drawings, E are allowed to work, the said gnideway being in which like letters of reference indicate corl formed byhorMentally-disposed rods or bars 9 2 5 responding parts in each of the several fig 3 g, which extendalittle beyondthe limit of the ures, Figures 1 and-fare side elevat ions show- 1 outwardmovement of the arms.

Said sleeves tion taken on line Fig. 1i is a partial side 1: are held rigidly upon said standard, stud, or view showingcertain springs connecting with shaft by frictional contact or otherwise, turnthe conductingavires. Fig. 15 is a section ing therewith, and upon the outer sleeve is 5 taken on line of. fixed a gear or cog wheel, 7., by means of In said drawings, a indicates a snit-al lle bed, which motion is transmitted from the electric upon which is secured a bearing-plate, a, as motor to the governor. At the outer ends of indicated in Fig. 4, in which is fixed a revolvthe bars g, which are preferably segn'iental ing standing stud or shaft, b. Said stud, post, and concentric with the path of the governing- 50 or shaft 1) may be provided with bearings arms, are formed contact points or bearings above said plate a to give greater firmness g g, which may be either rigidly fixed or formed 011 said bars, as in Fig. 9, or have a spring backing, as in Fig. 10, whereby no jar will be produced when said bearings are engaged by the governing-arms;

To make a more perfect contact, the arms 0 may be projected or pointed when they are to engage said bearing g, as at c, and should the said arms be so arranged as that they would make an electrical contact with the sleeve 2' when at rest they may be insulated, as indicated in Figs. 7, 8, and 11 at h.

The poles of the electrical circuit to be governed are brought into connection with the shaft or standard I) by means of the conducting-wire m and metallic piece n, and with the metal sleeve 1' by means of the metal pieces 91 and 0, the said metallic pieces n and 0 being held on 'a suitable post, p, insulated therefrom, as indicated in Fig. 15, and providing suitable bearings for the shaft 1) and sleeve '27, so as to secure a perfect electrical connection, the said metallic pieces being preferably springs which bear against the sides of the shaft, and thus produce the desired connection. The stud 1) may be also provided with bearings for the main shaft 19 and co-operating gear or cog wheel 1) of the motor.

- In Fig. the metallic piece it is shown to be clamped between rubber washers t, and to be held upon the post 2) by a suitable pin or screw, and thus the said piece it is held from any electrical connection with the post p, as will be understood.

In operating the device the electrical current is brought through a divided circuit from the battery on the wire or to the spring 0, from whence it travels over the sleeve '2', bars 9, arms 0, (when said arms are in engagement with the contact points or bearings g,) and shaft 1) to the spring 02, as will be understood. lVhen the electro motor, to which the governor has been attached by means of the shaft p and wheels p 7. has attained a high rate of speed, and the weights (Z are thrown outward by the centrifugal force and brought into connection with the said bearings g, and thus a more direct circuit for the current is set up as a result, the current is diverted from the motive mechanism, and thus the speed of the motor is reduced, and is thus kept within the desired limit, as will be understood.

Having thus described the invention,what I claim as new is 1. In combination, in an electric governor, with the shaft b and weighted arms 0 c, and a sleeve, 1', insulated from said shaft, a bar or bars, g, having bearings g, adapted to make an electrical contact with said weighted arms, substantially as and for the purposes set forth.

2. In an electrical governor, the combination, with a revolving shaft and governingarms adapted to be acted upon by centrifugal force, of contact bearings or points arranged on the path of said governing-arms and connected with a sleeve arranged on said shaft, and conducting-pieces n 0, arranged in connection with said shaft and sleeve, respectively, substantially as and for the purposes set forth.

3. In an electrical governor, the combination of a revolving shaft having governingarms adapted to be acted upon by centrifugal force, an insulated sleeve and bars g, having bearings g in electrical connection with said sleeve, a gear-wheel, 7:, arranged in connection with the main shaft of the motor, and springs 0 n, bearing on said sleeve and shaft, respectively, substantially as and for the purposes set forth. 4

5. In combination with the shaft 1) and governing-arms, bearings g, and conductors connecting with said bearings and shaft, and insulators interposed between said bearings and shaft, substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 11th day of July, i888.
